I remember that DirecTV had the Major League Baseball Extra Innings — it’s their baby, I believe — and had both broadcasts of any out-of-market game. (For example, if the Yankees are playing the Red Sox, unless you’re in New York or Boston, you could get either the Yankees broadcast or the Red Sox broadcast.)
They also had something called Sports Pack, which got you regional sports networks from around the country, and if you had both you never actually had to use the Extra innings channels, as tehy would feed the game on the RSN.
